Examples

gr = GRanges(seqnames = c("chr5", "chr5"),
	ranges = IRanges(start = c(98, 98),
	                 end = c(104, 104)))
target = GRanges(seqnames = "chr5",
	ranges = IRanges(start = 100, 
		             end = 100))
mat1 = normalizeToMatrix(gr, target, extend = 6, w = 1)
# attributes removed and you cannot use it for EnrichedHeatmap()
mat2 = mat1[]
# copy attributes to mat2 and now mat3 can be used for EnrichedHeatmap()
mat3 = copyAttr(mat1, mat2)
